7x+2 is the equation because each pizza cost 7 dollars and the y-intercept is at 2
I think the answer is 745
Answer:
3*2-7y=9
or,6-7y=9
or,-7y=9-6
or,-7y=3
or y=3/-7
therefore the value of y=3/-7
First go to the y intercept (or the b in y=mx+b) look for the slope and plot the points on the graph they're talking about e.g. #23 the y-intercept is 6 go to the 6 on the y axis, and then look at the slope (x), so it goes up and over to the right since it's positive by 1
